Baby boys born through IVF have been found to have low sperm counts and may not be able to conceive children of their own naturally, according to a new study. Belgian doctors who pioneered the intracytoplasmic sperm injection (ICSI) form of IVF in the 1990s have been tracking 54 children born through the method since. They found that the 54 men now aged between 18 and 22, had almost half the sperm concentration of naturally conceived men as well as a 62 per cent lower sperm count, and 66 per cent lower sperm motility – which measures how well a sperm can move. In addition, they were discovered to be nearly four times more likely to have sperm counts below the level deemed ‘normal’ by the World Health Organisation.
